Goodfire Launches Internal AI Agent Monitors

Goodfire, a startup specializing in AI interpretability, launched on Thursday a new type of AI agent monitor that inspects a model's internal signals rather than reading its output, aiming to detect rogue behaviors more efficiently and at a fraction of the cost. The monitors are available to customers of Baseten, an AI model hosting platform. Baseten's Base Labs had previously announced a safety partnership with Goodfire and Hugging Face. Goodfire's approach uses small probes that scan a model's internal activations at each step, triggering a closer AI review only when flagged. In tests on the Kimi K3 model, Goodfire's monitors caught 94% of malicious hacking sessions and cost about $51 for 1,500 sessions, compared to $233 for a cheaper model and $10,000 for a top-tier one. The company positions the solution for open models, which can be stripped of safeguards, and sees it as critical for inference-time guardrails.

• Goodfire launched internal activation monitors for AI agents on October 8, 2026.
• Monitors are available to Baseten customers.
• In tests on Kimi K3, monitors caught 94% of malicious hacking sessions.

Baseten, Hugging Face, Goodfire Partner for AI Safety

Baseten's research arm, Base Labs, announced a partnership with Hugging Face and Goodfire AI to establish a safety standard for open-weight AI models. The collaboration aims to develop and publish methods for training and monitoring these models, making safety an integrated feature rather than an afterthought. This comes amid rising concern over 'abliteration,' a technique that removes safeguards from open models, with Hugging Face listing over 6,000 such models. The companies have not detailed technical specifics, but Goodfire's expertise in AI interpretability is expected to play a key role. This initiative seeks to leverage openness as an advantage for safety, providing transparent controls and encouraging community contributions.

• Baseten launched a safety infrastructure standard via Base Labs.
• Partnership with Hugging Face and Goodfire AI announced.
• Hugging Face hosts over 6,000 abliterated models.

Janus Henderson Fund Manager Defends CoreWeave Debt Stake

John Lloyd, global head of multi-sector and corporate credit at Janus Henderson, whose fund owns CoreWeave 9.75% bonds due in 2031, sees a buying opportunity despite market skepticism. CoreWeave's debt is distressed with yields above 15%, and its stock has tumbled, but Lloyd believes the selloff is an overreaction. The company has roughly $51.6 billion in total debt and a debt-to-equity ratio of 702%. Analysts expect revenue and EBITDA to ramp up next year, but capital expenditures will also grow. Lloyd suggests CoreWeave can use creative funding methods, such as GPU financing or increased customer prepayments, and notes the company has no near-term maturities. He also highlights tight supply-demand dynamics in AI compute and potential IPOs from Anthropic and OpenAI as supportive factors.

• CoreWeave has roughly $51.6 billion in total debt, including about $35 billion in notes, bonds and loans.
• CoreWeave's 9.75% bonds due 2031 yield to maturity is 15.97%, up over 70% since issuance.
• CoreWeave's stock tumbled 20% over the past week, and its five-year credit default swap spread is nearly 1,081 basis points.

HSBC warns CoreWeave shares to drop over 30%

HSBC has issued a 'reduce' rating on CoreWeave, a cloud infrastructure provider for AI workloads, with a price target of $39, implying a 36% downside from the previous close. The bank cites structural concerns for 'neoclouds', including CoreWeave's high debt load of over $51 billion and weak return on invested capital (8.9% average 2026-30, below its borrowing cost). Credit default swaps have reached distress levels, and the stock has already fallen more than 25% last week and over 21% in the last five days. HSBC also notes moderating revenue from large language models. The call is contrarian, as most analysts (32 of 45) have buy or strong buy ratings, according to LSEG data.

• HSBC initiated a 'reduce' rating on CoreWeave with a price target of $39 per share, implying 36% downside.
• CoreWeave has accumulated over $51 billion in debt to fund its AI infrastructure build-out.
• The company's credit default swap spreads reached distress levels last week.

AI Rally Fades as Neoclouds Fall, IPO Dives

Wall Street's AI rally stalled in Asia and Europe, with neocloud stocks like CoreWeave facing selling pressure despite a Goldman Sachs upgrade. Meanwhile, South Korean AI data center firm Elice saw its shares plunge over 30% on debut, highlighting IPO market jitters. Attention turns to earnings from Netflix and SpaceX, both reporting after the close. Nvidia announced a strategic cooperation with Germany and plans to invest nearly $10 billion in European companies and research institutions. Geopolitical tensions and rising oil prices add to market uncertainty.
